Uniaxial Compression Test of Honeycomb Using Only an Orphan Mesh
Uniaxial Compression Test of Honeycomb Using Only an Orphan Mesh
(OP)
Firstly, I have very little Abaqus experience. I have generated a relatively large mesh (~1.2M hex elements) using a program other than Abaqus and have imported it to Abaqus CAE. I now wish to perform a simple uniaxial compression test to obtain the stress-strain curve (elastic-plastic); however, I am struggling to apply BCs & loads etc. I seem to be able to apply them to individual nodes but there are to many to select them all manually. Is it possible to achieve my desired outcome using an orphan mesh alone (without geometry)? If so, any assistance would be greatly appreciated. Or if not, please can someone advise on how to proceed?
The attached image shows a single cell of the honeycomb, the full structure has 8x8 cells. I wish to apply the compressive load in the z-direction (whilst constraining the opposite face in the z-direction).
Thanks

The problem I'm having when creating the node set is that there are no features (since there is only an orphan mesh so no geometry), this makes selecting the nodes to include in the set very tedious.

Thanks, this has helped quite a lot - I still need to select each honeycomb cell individually, but it is a vast improvement over having to select each node!

Can you use shells and/or exploit symmetry to simplify your problem significantly?

You could try using the python getByBoundingBox() method or similar.
